Naphthalene can be hydrogenated under high pressure in the presence of metal catalysts to give 1,2,3,4-tetrahydronaphthalene(C10H12), also known as tetralin. [36] Both male and female rats exhibited evidence of carcinogenesis with increased incidences of adenoma and neuroblastoma of the nose. In China, the use of naphthalene in mothballs is forbidden. Naphthalene sulfonic acids are also used in the synthesis of 1-naphthol and 2-naphthol, precursors for various dyestuffs, pigments, rubber processing chemicals and other chemicals and pharmaceuticals.[22]. The point group symmetry of naphthalene is D2h. [13] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. These products are commercially sold as superplasticizers for the production of high strength concrete. 49 ($0.22/Count) There are four reaction steps involved in this synthesis. Chemical Synthesis (30) Materials Science (8) Molecular Biology (3) Research Essentials (2) Special Grade. Quote: 1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C10H7CH2CO2H. In the past, naphthalene was administered orally to kill parasitic worms in livestock. [45] Danger to human health and the common use of natural camphor are cited as reasons for the ban. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms. As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). [41] Naphthalene's minimum odor threshold is 0.084 ppm for humans. Oxidation with O2 in the presence of vanadium pentoxide as catalyst gives phthalic anhydride: This reaction is the basis of the main use of naphthalene. AldrichCPR (1) ... naphtalene acetic acid. It is used in pyrotechnic special effects such as the generation of black smoke and simulated explosions. ... Search results for naphthalene dicarboxlic acid at Sigma-Aldrich Female mice exhibited some evidence of carcinogenesis based on increased incidences of alveolar and bronchiolar adenomas of the lung, while male mice exhibited no evidence of carcinogenesis. Because of this resonance, the molecule has bilateral symmetry across the plane of the shared carbon pair, as well as across the plane that bisects bonds C2-C3 and C6-C7, and across the plane of the carbon atoms. For example, chlorination and bromination of naphthalene proceeds without a catalyst to give 1-chloronaphthalene and 1-bromonaphthalene, respectively. This colorless solid is soluble in organic solvents. Naphthalene is a repellent to opossums.[31][32]. In electrophilic aromatic substitution reactions, naphthalene reacts more readily than benzene. Two isomers are then possible for mono-substituted naphthalenes, corresponding to substitution at an alpha or beta position. Mey) suspension culture and ginsenoside synthesis were investigated. A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. Unlike benzene, the carbon–carbon bonds in naphthalene are not of the same length. Molten naphthalene provides an excellent solubilizing medium for poorly soluble aromatic compounds. The single largest use of naphthalene is the industrial production of phthalic anhydride, although more phthalic anhydride is made from o-xylene. It is best known as the main ingredient of traditional mothballs The shared carbons are labeled 4a (between 4 and 5) and 8a (between 8 and 1). NAA is a broad-spectrum plant growth regulator. These 1,8-dilithio derivatives are precursors to a host of peri-naphthalene derivatives.[21]. It was once the primary ingredient in mothballs, although its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. 多くの翻訳例が、活動分野別にソートされています “naphthalenesulfonic acid” – 英語-日本語 辞書スマート翻訳アシスタント。 For purpose of the standard IUPAC nomenclature of derived compounds, those eight atoms are numbered 1 through 8 in sequence around the perimeter of the molecule, starting with a carbon adjacent to a shared one. Alkyl naphthalene sulfonate are surfactants, The aminonaphthalenesulfonic acids, naphthalenes substituted with ethers and sulfonic acids, are intermediates in the preparation of many synthetic dyes. Acetic Acid is a synthetic carboxylic acid with antibacterial and antifungal properties. In industrial practice, distillation of coal tar yields an oil containing about 50% naphthalene, along with twelve other aromatic compounds. �_0$;H(@L�a���Ҍ@݆�F��3(Hs30X˲n RV�sVC3� 0 �>/OCGs[1174 0 R]>>/Pages 1149 0 R/StructTreeRoot 85 0 R/Type/Catalog>> endobj 1153 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/StructParents 0/Type/Page>> endobj 1154 0 obj <>stream Petroleum-derived naphthalene is usually purer than that derived from coal tar. Naphthalene is the most abundant single component of coal tar. In North America, the coal tar producers are Koppers Inc., Ruetgers Canada Inc. and Recochem Inc., and the primary petroleum producer is Monument Chemical Inc. [14] Naphthalene's chemical formula was determined by Michael Faraday in 1826. The Occupational Safety and Health Administration has set a permissible exposure limit at 10 ppm (50 mg/m3) over an eight-hour time-weighted average. [29] The aromatization of hydroporphyrins has been achieved using a solution of DDQ in naphthalene.[30]. Power Grown's offers Naphthalene Acetic Acid 98% 10 Grams water soluble Tech grade for only $12.99. Naphthalene: Uses, Hazards & Safety ...

Alkyl naphthalene sulfonates (ANS) are used in many industrial applications as nondetergent wetting agents that effectively disperse colloidal systems in aqueous media. Synthesis of Thiophene‐annulated Naphthalene Diimide‐based Small‐Molecular Acceptors via Two‐step C−H Activation. [27], Protonated cations of naphthalene (C10H+9) are the source of part of the spectrum of the Unidentified Infrared Emissions (UIRs). In Western Europe the well-known producers are Koppers, Ruetgers, and Deza. Bicyclo[6.2.0]decapentaene is a structural isomer with a fused 4–8 ring system[18] and azulene is another, with a fused 5-7 ring system. Naphthalene sulfonic acids are used in the manufacture of naphthalene sulfonate polymer plasticizers (dispersants), which are used to produce concrete and plasterboard (wallboard or drywall). Further hydrogenation yields decahydronaphthalene or decalin (C10H18). ���A,dk'(�0582p$0�;(50?fhS�����B�q ��c�]C6�� The IARC also points out that acute exposure causes cataracts in humans, rats, rabbits, and mice; and that hemolytic anemia (described above) can occur in children and infants after oral or inhalation exposure or after maternal exposure during pregnancy. In a sealed container containing naphthalene pellets, naphthalene vapors build up to levels toxic to both the adult and larval forms of many moths that attack textiles. The chief impurities are the sulfur-containing aromatic compound benzothiophene (< 2%), indane (0.2%), indene (< 2%), and methylnaphthalene (< 2%). This research has been publicized as "mothballs in space."[28]. The 1-isomer forms predominantly at 25 °C, and the 2-isomer at 160 °C. Many azo dyes are produced from naphthalene, and so is the insecticide 1-naphthyl-N-methylcarbamate (carbaryl). Naphthalene sulfonate polymers are produced by treating naphthalenesulfonic acid with formaldehyde, followed by neutralization with sodium hydroxide or calcium hydroxide. The major commercial applications are in the agricultural chemical industry, which uses ANS for wettable powder and wettable granular (dry-flowable) formulations, and the textile and fabric industry, which utilizes the wetting and defoaming properties of ANS for bleaching and dyeing operations. However, the solid shows semiconducting character below 100 K.[19][20]. The reaction of C60 with anthracene is conveniently conducted in refluxing naphthalene to give the 1:1 Diels–Alder adduct. It features a carboxylmethyl group (CH2CO2H) linked to the "1-position" of naphthalene. Hydrogenation of naphthalene gives tetralin, which is used as a hydrogen-donor solvent. For beta substitution, the intermediate has only six resonance structures, and only two of these are aromatic. h��Zmo�6�+��`��wR� ��`i�$[� ���Zj���ۚ�;���-'q�Z��yw3�P˜��Q��"̺M8u�!\d,�V!S%0 hKԲ��N�r��QȂ Analogous to the synthesis of phenyllithium is the conversion of 1-bromonaphthalene to 1-lithionaphthalene, a lithium-halogen exchange: The resulting lithionaphthalene undergoes a second lithiation, in contrast to the behavior of phenyllithium. "naphthalene cation" (C10H+9) have been observed by astronomers. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. Naphthalene is used mainly as a precursor to other chemicals. The molecule is planar, like benzene. Please include product name, order quantity, usage, special requests if any in your inquiry. 1151 0 obj <> endobj (In organic chemistry, rings are fused if they share two or more atoms.) Humans, in particular children, have developed the condition known as hemolytic anemia, after ingesting mothballs or deodorant blocks containing naphthalene. "[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively. Most naphthalene is derived from coal tar. With alkali metals, naphthalene forms the dark blue-green radical anion salts such as sodium naphthalenide, Na+C10H−8. He proposed the name naphthaline, as it had been derived from a kind of naphtha (a broad term encompassing any volatile, flammable liquid hydrocarbon mixture, including coal tar). endstream endobj startxref The bonds C1−C2, C3−C4, C5−C6 and C7−C8 are about 1.37 Å (137 pm) in length, whereas the other carbon–carbon bonds are about 1.42 Å (142 pm) long. Exposure to large amounts of naphthalene may cause confusion, nausea, vomiting, diarrhea, blood in the urine, and jaundice (yellow coloration of the skin due to dysfunction of the liver).[35]. Naphthaleneacetic acid Synthesis. 1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C10H7CH2CO2H. In Eastern Europe, naphthalene is produced by a variety of integrated metallurgy complexes (Severstal, Evraz, Mechel, MMK) in Russia, dedicated naphthalene and phenol makers INKOR, Yenakievsky Metallurgy plant in Ukraine and ArcelorMittal Temirtau in Kazakhstan. Symptoms include fatigue, lack of appetite, restlessness, and pale skin. Naphthalene has been used as a household fumigant. They are also used as dispersants in synthetic and natural rubbers, and as tanning agents (syntans) in leather industries, agricultural formulations (dispersants for pesticides), dyes and as a dispersant in lead–acid battery plates. They are: First step: Extraction of Naphthalene from coal tar Second step: Preparation of α-Chloromethyl naphthalene from naphthalene Third step: Preparation of α-Naphthyl acetonitrile from - α Chloromethyl naphthalene Fourth step :Preparation of Naphthalene acetic acid (NAA) Protonated naphthalene differs from neutral naphthalene (e.g. The National Institute for Occupational Safety and Health has set a recommended exposure limit at 10 ppm (50 mg/m3) over an eight-hour time-weighted average, as well as a short-term exposure limit at 15 ppm (75 mg/m3). Naphthalene is used in engineering to study heat transfer using mass sublimation. The selectivity for alpha over beta substitution can be rationalized in terms of the resonance structures of the intermediate: for the alpha substitution intermediate, seven resonance structures can be drawn, of which four preserve an aromatic ring. This difference, established by X-ray diffraction,[17] is consistent with the valence bond model in naphthalene and in particular, with the theorem of cross-conjugation. Cell suspensions were grown for 6–8 subcultures on media supplemented with various phytohormones. The International Agency for Research on Cancer (IARC)[37] classifies naphthalene as possibly carcinogenic to humans and animals (Group 2B). Pure crystalline naphthalene is a moderate insulator at room temperature, with resistivity of about 1012 Ω m. The resistivity drops more than a thousandfold on melting, to about 4 × 108 Ω m. Both in the liquid and in the solid, the resistivity depends on temperature as ρ = ρ0 exp(E/(k T)), where ρ0 (Ω m) and E (eV) are constant parameters, k is Boltzmann's constant (8.617×10−5 eV/K), and T is absolute temperature (K). In 1821, John Kidd cited these two disclosures and then described many of this substance's properties and the means of its production. Although its mechanism of action is not fully known, undissociated acetic acid may enhance lipid solubility allowing increased fatty acid accumulation on the cell membrane or in other cell wall structures. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. Effects of synthetic auxins (2,4-D and NAA) on growth of true ginseng (Panax ginseng C.A. ... (NAPHTHALENE-1-SULFONYLAMINO)-ACETIC ACID ETHYL ESTER. [42], Mothballs and other products containing naphthalene have been banned within the EU since 2008.[43][44]. Although the composition of coal tar varies with the coal from which it is produced, typical coal tar is about 10% naphthalene by weight. [38] A probable mechanism for the carcinogenic effects of mothballs and some types of air fresheners containing naphthalene has been identified. Other useful agrichemicals include naphthoxyacetic acids. Sulfonation to give the 1- and 2-sulfonic acid occurs readily: Further sulfonation give di-, tri-, and tetrasulfonic acids.

The naphthalenide salts are strong reducing agents. Oxidation can also be effected using conventional stoichiometric chromate or permanganate reagents. [39][40], US government agencies have set occupational exposure limits to naphthalene exposure. Naphthalene is an organic compound with formula C 10 H 8.It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. Thus there are two sets of equivalent hydrogen atoms: the alpha positions, numbered 1, 4, 5, and 8, and the beta positions, 2, 3, 6, and 7. The crude naphthalene resulting from this process is about 95% naphthalene by weight. Other fumigant uses of naphthalene include use in soil as a fumigant pesticide, in attic spaces to repel animals and insects, and in museum storage-drawers and cupboards to protect the contents from attack by insect pests. %PDF-1.6 %���� [25][26] More than 20% of the carbon in the universe may be associated with polyaromatic hydrocarbons, including naphthalene. Where required, crude naphthalene can be further purified by recrystallization from any of a variety of solvents, resulting in 99% naphthalene by weight, referred to as 80 °C (melting point). It features a carboxylmethyl group (CH2CO2H) linked to the "1-position" of naphthalene. Under California's Proposition 65, naphthalene is listed as "known to the State to cause cancer". ChemInform Abstract: Synthesis and Antiinflammatory Activity of Some New 6-Methoxy-α-methyl-2-naphthalene Acetic Acid Derivatives August 2010 ChemInform 30(31) Chemistry – An Asian Journal 2019 , 14 (10) , 1651-1656. [33] It is used to create artificial pores in the manufacture of high-porosity grinding wheels. The structure of two fused benzene rings was proposed by Emil Erlenmeyer in 1866,[15] and confirmed by Carl Gräbe three years later.[16]. This colorless solid is soluble in organic solvents. This oil, after being washed with aqueous sodium hydroxide to remove acidic components (chiefly various phenols), and with sulfuric acid to remove basic components, undergoes fractional distillation to isolate naphthalene. Naphthalene and its alkyl homologs are the major constituents of creosote. In the early 1820s, two separate reports described a white solid with a pungent odor derived from the distillation of coal tar. Exposure to large amounts of naphthalene may damage or destroy red blood cells, most commonly in people with the inherited condition known as glucose-6-phosphate dehydrogenase (G6PD) deficiency,[34] which over 400 million people suffer from. [24], Naphthalene has been tentatively detected in the interstellar medium in the direction of the star Cernis 52 in the constellation Perseus. 1172 0 obj <>/Filter/FlateDecode/ID[<8788FF9F3E389742991234F683D9B24D>]/Index[1151 49]/Info 1150 0 R/Length 105/Prev 630474/Root 1152 0 R/Size 1200/Type/XRef/W[1 3 1]>>stream Member Is Offline. Sulfonation gives the "alpha" product naphthalene-1-sulfonic acid as the kinetic product but naphthalene-2-sulfonic acid as the thermodynamic product. In many cases it is more efficient than other high-boiling solvents, such as dichlorobenzene, benzonitrile, nitrobenzene and durene. From the 1960s until the 1990s, significant amounts of naphthalene were also produced from heavy petroleum fractions during petroleum refining, but today petroleum-derived naphthalene represents only a minor component of naphthalene production.
